JCarousel Center slide, circular wrap issue

Question

Created a slider with Wrap = circular and center = true,

Left is always blank. I tried editing the source to prepend last few siblings to the first but didn't work. How do I get seemless left/right scroll with active center slide

$('.jcarousel')
     .jcarousel({

     wrap: 'circular',
     center: true
 });
